Azimuthal single‐spin asymmetries (SSA) in semi‐inclusive electroproduction of charged pions in deep‐inelastic scattering (DIS) of positrons on a transversely polarised hydrogen target are presented. Azimuthal moments for both the Collins and the Sivers mechanism are extracted. In addition the subleading‐twist contribution due to the transverse spin component from SSA on a longitudinally polarised hydrogen target is evaluated.
